For Online Computer Support, Ask a Computer Technician
I am Stefan and will be glad to help. So you cant turn it on or off?
If you really need your files I can recommend a great company that can recover your data if you like.
Like I said if you like I can give you info to a data recovery company. A good computer shop should also be able to pull the drive and back it up. Then you can reset the computer but have data backed up.
Don't forget to give me rating of 3+ to credit my work.
